Specification forming part of Letters Patent No. 9?,53ll, dated December 7, 1869.

To all whom it mag concern Be. it known that I, SYLVANUS DL LOGKE,

' of Janesville, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Grain-Binders; and

. I do hereby declare thatthe following is a full,

clear, and exact description thereof, reference being had to the accompanying drawings,

making a part of this specification, in Which- .Fignre 1 is a side view. Fig. 2 is a top view.

Fig. 3. is a side view of the camand arms for.

bearingthe binding-material around the'bun- -dle.- Fig. 4 is a side view of the operating parts of the sheaf-discharging device. Fig. 5 is a longitudinal section of the crank and its connections. Fig. 6 is a longitudinal section through the. spring E, Figs. 1 and 2. Fig. 7-

is a side view of the cam and armfor compressing the bundle. Fig. 8 is a side view of the cam and arm for operating the tying or twisting device. Fig. 9 is a transverse section through the disengaging-cou-pling, showing thedisengaging-lever. Fig. 10 is a longitudinal section througl-l the support d, Figs. 1 and 2. Fig-19% is a longitudinal section through the eouplin g and universal joint. Figs. 11, 12, and 13; are side views of the compressing, binding, and tying or twistfing arms, with their operating mechanism. showing them detached from the frame and other parts, and in three of the difierentpositions which they assume during a revolution of their operatingcrank. Fig. 14; is a longitudinal section of the reel. Fig. 15 is a front view of the same, with a portion of the body of the reel broken away. Fig. 16 is a rear view oft-he same.

Fig. 1, Plate 3, is also aside view, showing a combination of thecompressing and binding mechanism; and Fig. 2, Plate 3,'is the same as the last, but with the spring differently atiached.

. The nature-of my invention relates tothe hand-carrying and compressing arms of a grain-binder, with their operating mechanism; to the mechanism for operating the hand-securing devices of grain-binders; to a new and improved mode of operating a slieai'- i liscliarg= 'ing device, and to a new and improved takenp reel; and consists in the use of the devices hereinafter more particularly descrlbed.

7 To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation. 7

Inthe'drawings, A represents a shaft, tak-' ing power from a harvester; B the ball, 0 the socket, and a the pin,*ot' a universal joint; A,

the main drivingshat't of the grain-binder,

(taking bearing on the frame N N N, or upon "any suitablesupport on the end of which isa crank, K, having a'wrist-pin, P, that plays in the grooves of the cam-arms D, D, and D,

that are pivoted on the shaft or stud M.

The'ca-m-arin-D isjoined ,by-a spring, E,

and a stopping-bolt, more particularly shown in Figs. 6 and 7, to the arm 13", that is also pivoted on the shaft or stud M. On the arm F! is a segmental gear, F, working in a seg-.

mental pinion, G, on the end of the compressing-arm H. Attached to the cam-arm D, and

making a part thereof, is the arm I and the segmental gear F, shown more particularlyin Fig. 3. i

The arml bears the twisting-or tying mechanism, represented by G 'B, and the wire or cord holder, represented by C, while the segmental gear F works in the segmental pinion G, on the end of the wire or cord bearing arm J. I

' The camarm D has attached thereto the tyingor twisting arm Z, that, by means of the rack A, operates the-tying or twisting nech.

anism.

On the main shaft A is a cam-lug, Q,.tha;t, revolving with the shaft, as shown in Fig. 4, operates the working beam or lever Q, that is. pivoted on a shaft or stud, M, and. is attached, by means of connecting rod or pitman R, to the crank S, on the shaft or pivoted portion of the sheaf-discharging arm V, w ch shaft or pivoted'por'tion take-shearing in a standard,

as shown, or in any'snitable support.

To prevent'the great lateral strain,'incideiitto disengaging the couplingv S, tearing the disengaging-lever b from its support 0 con the frame N, I extend it over thecou sling in the form of a lever, b, as shown in *igs. 2 and 9, and allow this lever to work against a finger,

(1 that, extending out from the frame N,.turns Y up so as to'form a lateral support, as shown more particularly in Fig. 10.

X is a grain-guard,.-and Y an extension of the reaper-platform.

The reel F plays loosely that turns freely upon the smaller portion m of the stud M, Figs. 14, 1.5, and 16.

The sleeve is kept in position on the stud m by a pin, it. or in any other suitable manner. The rear portion of the sleeve is enclarged, so as to form a brake, t, against which the reel-body F is pressed with any desired force by the spring r and nut p on the outer end of the sleeve.

()n the stud M is a spring, 11, that has one end attached firmly to a pin, y, or otherwise, in the lixed stud M, while the other end is at tnched to a pin, a, on the brake portioirof the sleeve, thereby joining the sleeve to the stud, and allowing the former to play upon the latter only so far as the limited movement of the spring v will permit.

The cam-arm l), with the segmental gear and pinion 1 and G, and arms I and J, may be dispensed with, it thought desirable, by simply extending the cam-arm, so as to form a secondary arm, I, for the support of the parts B, C, and G, and allowing the, compressing-arm H to bear the binding material, as shown in Fig. 1, Plate 3. Or the segment nl gear 1*",i'ii last-named figure, may be attached directly to the cam-arm I), while the spring-arm 1 is attached to the segmental pinion G, and the spring l) interposed between ii, *he -pring-nrni 1, and the arm H, as shown'in Fig. 2, Plate :5. l prefer either of the modincni ions shown'in Plate 3 to the mode ol' constructing the parts first described.

When in o )Ul'iltlilll. the crank K turnin in the direction indicated by the arrow in Figs. 1, I), and -;i, and the-arms being open, with the wire or cord drawn up out. of the way of the incoming gavel, as shown in Fig. 13, the more intent of the arms is such as to first compress the bundle, and loop around it the binding material, as shown in Fig. 11. Then, the crank continuing to turn, the form of the camnrnis is such that the arms H and J, or the arm ll alone,'it' only that be used, hold the bundle compressed and the binding material looped around it, as in Fig. 11, while the arm Z, moving, operates the tyingor twisting mechanism G 13, thereby twisting or otherwise securing the band, as shown in Fig. 12.

upon a sleeve, 25,-

At this stage of the operation, the form of the grooves in the cam-arms is such as to cause the arms H and J to partly open, as shown in Fig. 12, thereby loosening the bundle, and al-.

lowing the sheaf-discharging arm V, moved at the proper time by the cam-lug Q, to sweep it endwise'oii the platform Y, when the arms again open to the first position shown in Fi 13, the spring U returning the sheat-discharg ing arm, and so continuously.

As the arms open the pin or lug e, outhe disengaging-coupiing, striking against the inolined portion of the disengaging-lever 7) b, causes the couplings to disengage, and the movement of the various parts to cease until the lever 11 b is raised, as shown by dotted lines in Fi 9, when the spring R forces the couplings together, and the movement of the parts, as above described, is repeated.

The turning of the reel-body F, as the binding material is withdrawn from it, coils up the spring v until its elasticity equals the force necessary to overcome the friction of the reel against the brake t, when the former slips over the face of the latter, so allowing the binding material to be withdrawn without further coiling up the spring 12.

It' at any time there should he slack wireor cord, the spring o causes the reel-body and sleeve to revolve backward on the stud or spindle m, so taking up the slack and keeping the binding material taut,

To insure the te sion on the binding material, it is only necessary to run up the nut 1;, thereby pressing the reel-body F with in' creased force against the brake t. when the spring n will be coiled up still further to obtain the requisite elasticity to overcome the increased friction on the brake.

hat 1 claim is- 1. The combination of the cam-arm D with the binding-arms I J, substantially as described.

2. The finger d and lever b, for supporting the disengaging part b, substantially as described. SYLVANUS D. LOOKE.
